Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Guide in the process of being made, please be patient (still doing theory crafting)
Go heavily after Cooldown Reduction and Attack Damage (build somewhat like a bruiser)
Tryout how well Trinity Force works, otherwise stick to either Guardian Angel or Warmog's Armor
Work on new build with introduction of new items
